irssi consistently segfaults

[irssibot]

• • • Issue #397 opened by @maddhatter

Irssi is running within screen version 4.00.02 (FAU) 5-Dec-03 connected via SSL (v. 0.9.8) to an unreal server. I cannot cause the segfault at will, but it happens consistently at least once every several days. Irssi frequently freezes for 30sec up to a few minutes just before the segfault.

Is it still reproducible with irssi-0.8.12 ?

This bug can happen with <= glib-2.2.1, because g_io_error_get_from_g_error assume err != NULL in those versions and irssissl{read,write} do not set the 'gerr' argument.
